FRANK S. HERETI-I, OF NEW YORK, N. Y., ASSIGNOR TO E. R. SQUIBB & SONS, A CORPORATION OF NEW YORK.

HERME'IIC SEAL FOR RECEPTACLES.

To all whom it may concern:

Be it known that I, FRANK S. Hnnn'rri, a citizen of the United States, residing at the city of New York, in the borough of Brooklyn and State of New York, have invented certain new and useful Improvements in Hermetic Seals for Receptacles, of which the following is a. full, clear, and exact de scription.

The invention relates to bottles and other receptacles, the same being especially designed for use with glass bottles adapted to contain highly volatile substances such as chloroform, ether, and the like.

Attempts have been made heretofore to provide hermetic seals for vitreous receptacles by casting, cementing, embedding or otherwise securing a metallic seal-seat to the mouth of the receptacle to form a base to which the seal itself may be secured, but it has been found to be practically impossible to obtain an absolutely impervious joint between the mouth of the bottle and the sealseat. Where heat is used to secure the sealseat to the mouth of a vitreous receptacle the differences between the coefficients of ex pansion of the metal and the vitreous substance is suflicient to cause the fracturing or crushing of the mouth of the receptacle by the shrinking of the metal seat upon cooling. This has necessitated the interpositioning of a yielding medium between the mouth of the receptacle and the seal-seat, but as such a medium is necessarily porous its use is highly objectionable where a perfectly impervious joint is essential.

The object of my invention is to overcome these objections to the use of metallic sealseats and, in addition, to provide a sealseat, in combination with a hermetic seal, which may be readily secured to the receptacle adjacent to the mouth thereof and yet be joined thereto in such a manner that an absolutely impervious joint is obtained between the receptacle and the seal-seat.

My invention therefore consists of the bottle or receptacle, having a layer of metal electroplated thereto, adjacent its mouth, the said layer of metal forming a base or seal-seat, and a seal secured to said seat for hermetically closing the receptacle.

In the drawing wherein like reference characters refer to like parts, Figure 1 is an Specification of Letters Patent.

elevation of a receptacle having its mouth hermetically closed with my improved form of seal; Fig. 2 is a vertical section of the same, showing the seal and seal-seat.

The bottle 1, of glass or other vitreous material, is provided with the usual neck 2 havlng a flange 3 surrounding the mouth of the bottle. A layer or band 4t of nickel, silver or other metal, is applied to the flange 3 by any of the well known processes for electroplating metal on glass or other vitre' ous substances. This metallic layer or band 4 has been shown as extending over the top and sides of the flange 3 and forms a sealseat or base to which may be secured a seal 5. It is obvious, however, that this band or seal-seat may be located at any suitable point 011 the bottle, adjacent the mouth thereof. The seal 5 is preferably a metallic disk of soft metal, such as lead or the like, the peripheral edges of which are fused, soldered or otherwise secured to the seal-seat 4 to hermetically close the bottle.

It is evident that by electroplating the layer or band 4 to the bottle an intimate contact is obtained between the vitreous substance of which the bottle is made, and the metal, which will be so perfect as to form an absolutely impervious joint between the two. The danger of leakage or loss of a liquid through the impervious joint thus obtained, even when a highly volatile liquid is contained within the receptacle, is thereby entirely eliminated.

hen it is desired to use the contents of the bottle, the seal 5 may be punctured or entirely removed from the seal-seat by heating the same, or in any other way, the particular manner in which the seal is opened forming no part of the invention.

Having now described my invention, what I claim, is

A sealing device for bottles comprising an electro-deposited layer of metal around the lip of the bottle in combination with a metallic disk closing the mouth of the bottle and soldered to said electro-deposited layer.

In witness whereof, I subscribe my signature, in the presence of two witnesses.
